Whereas the first appearance of anatomically modern humans in Western Europe seems to be well understood, the situation is quite different for Eastern Europe, where data are more scarce. The Buran-Kaya III site in Crimea is of key importance to understand the colonization of Europe by anatomically modern humans and their potential contemporaneity with the last Neanderthal occupations. The new radiocarbon dated sequence shows that no Neanderthal settlement existed after 39 ka cal BP and casts doubt on the survival, as previously proposed, of Neanderthal refuge zones in Crimea 28 ka BP ago (34-32 ka cal BP). The human remains from Buran-Kaya III, directly dated to 32450 +250/-230 BP (layer 6-2) and 31900+/-220 BP (layer 6-1) (37.1-35.7 ka cal BP and 36.3-35.2 cal BP respectively), represent some of the oldest evidence of anatomically modern humans in Europe...

The taxonomic allocation of this specimen is still under debate, as it has been attributed either to the genus Homo or Australopithecus. Two alternative hypotheses have been proposed regarding the taphonomic agent responsible for the linear marks observed on this specimen. These modifications were initially assigned to anthropic cutmarks inflicted by stone tools, thus representing the earliest cutmarks discovered on hominin remains. Conversely, these linear marks were interpreted by others as non-anthropic modifications. In order to better understand the origin of the linear marks, a new taphonomic appraisal of these modifications was conducted using a multivariate statistical approach complemented by butchery and trampling experiments on extant mammal bones. This new study of Stw53 linear marks does not provide evidence for anthropic activitie...

It is also frequently used to study, score, and compare morphological variations in fossil hominin taxa and to examine their phylogenetic relationships. However, using ASUDAS in studies of this type is under debate because it is based on modern Homo sapiens populations and does not appear to cover all variations observed in fossil Plio-Pleistocene homi- nins. Our observations and coding of 178 dentals casts of Plio-Pleistocene specimens based on ASUDAS and from the literature have confirmed the need to adapt the standard system to fossil hominins. In this initial study, we propose that the scoring procedures for some morphological characters need to be readjusted, while others could be standardized following the ASUDAS system.

Maintaining the balance between costs and benefits is challenging for species living in complex a... more Maintaining the balance between costs and benefits is challenging for species living in complex and dynamic socio-ecological environments, such as primates, but also crucial for shaping life history, reproductive and feeding strategies. Indeed, individuals must decide to invest time and energy to obtain food, services and partners, with little direct feedback on the success of their investments. Whereas decision-making relies heavily upon cognition in humans, the extent to which it also involves cognition in other species, based on their environmental constraints, has remained a challenging question. Building mental representations relating behaviours and their long-term outcome could be critical for other primates, but there are actually very little data relating cognition to real socio-ecological challenges in extant and extinct primates. Here, we review available data illustrating how specific cognitive processes enable(d) modern primates and extinct hominins to manage multiple r...
